Arrange aluminum, nitrogen, phosphorus, and indium in order of increasing electronegativity.

Question

Quizplus · Accepted Answer

Electronegativity increases as you move from left to right across a period in the periodic table, and decreases as you move down a group. Therefore, indium has the lowest electronegativity and nitrogen has the highest. Aluminum and phosphorus are in the same period, but since aluminum is a metal and phosphorus is a nonmetal, aluminum will have a lower electronegativity. Thus, the correct order of increasing electronegativity is In < Al < P < N.
